  • Patent number: 8598023
    Abstract: There is disclosed a substrate processing apparatus including a processing chamber housing a substrate, pipes for supplying gas into the processing chamber, and heaters provided in the middle of the pipes, and heating the gas. In the substrate processing apparatus, the heaters heat the gas to a temperature lower than a temperature at which exhaust gas is generated from the pipes to dry the substrate in the heated gas.
    Type: Grant
    Filed: July 31, 2012
    Date of Patent: December 3, 2013
    Assignee: Fujitsu Semiconductor Limited

  • Patent number: 7615431
    Abstract: Before applying a resist on a first gate insulating film, a thinner is provided on an entire surface including a surface of the first gate insulating film to wash the surface of the first gate insulating film. Specifically, while a semiconductor substrate is being rotated, onto a central part thereof the thinner is provided from a nozzle, so that the thinner is spread outward in a radial direction of the semiconductor substrate to be applied on an entire surface of the semiconductor substrate by a centrifugal force.

  • Patent number: 6835625
    Abstract: The method for fabricating a semiconductor device comprises the step of: forming a gate electrode on a semiconductor substrate with a gate insulation film formed therebetween; the step of implanting a dopant in the semiconductor substrate with the gate electrode as a mask to form a dope region in the semiconductor substrate; the step of forming a chemical oxide film on the doped region, which prevents the dopant implanted in the doped region from diffusing outside the semiconductor substrate; and the step of performing thermal processing for activating the dopant implanted in the doped region.
